SPECIFIGATION forming part of Letters Patent No. 509,319, dated November 21, 1893. Application filed March 8, 1893.l Serial No.465,150.` (No model.)

To all whom it' may concern.-

Beit known that I, SAMUEL WALKER LEWIS, ofk Brooklyn, Kings county, New York, have invented new and useful Improvements in Water-Closets and Urinal-Receptacles, of which the following is a speciication.

One part of my invention relates broadly to all forms of receptacles known as'siphon jet water closets and urinals, in which one or more jets, which I will term a jet flushing means, is employed to empty the bowl or to promote siphonic action, the object of this part of my invention being to prevent the noise when in action, caused by the .unchecked rush and escape of air' and Water through the outlet at the rim of the bowl,

and I attain this object by arranging the conduit, pipe, or delivery arm, which leads to the upper part of the bowl, in such manner that the contents of the supply or flush pipe will be carried to the jet and thence through a conduit leading from and beyond said jet beneath a water seal, preferably, though not essentially beneath the normal level of water inv the bowl before discharging at or to the rim of the bowl, whereby said conduit will be water sealed between the jet .and the rim delivery, so that the air in the supply or Hush-pipe may escape or be expelled through said jet or jets or sor far beneath the water as'to be noiseless.

Another part of my invention is to produce a more gentle flushing of the upper part of the bowl and an increased force of jet action, which object-I attain by increasing the length of the said conduit between'the jet discharge and the rim discharge, (so that the jet outlet may be nearer to the supply than the rim outlet) preferably by turning or coiling the said conduit leading to the rim delivery, whereby the increased length or turns in the channel, or both combined, causes a frictional resistance to the tlow through said conduit and consequently a more gentle flushing through the rim, thereby producing a back pressure which causes the confined fluids to pass with more velocity and force through the more direct jet outlet. This construction enables me, as a direct opposite to all previous methods, to dispense with valves or contractions of any of the parts and to make the branch supply or conduit leading to the rim delivery of full unrestricted size throughout its entire length.

Another part of my invention consists broadly in an auxiliary water supply contained in a reservoir below the normal water line and above the seal of any closet, bowl,

urinal or trap emptied by siphonage, or by means of a siphoning pipe or trap, said reservoir being formed by the conduit leading from the supply to the ushing means, the purpose of said auxiliary supplyV of water being to maintain a seal against siphonage or evaporation as will hereinafter appear.

In the annexed drawings, Figure l, is an external view in side elevation of a closet bowl having al jet at the bottom of its outlet connected directly with-a supply pipe by an extension entering at the side and provided with a conduit branching from said jet and leading by coils around the bowl and up to the rim delivery. Fig. 2, is a reverse view of the same showing the course of the coiled conduit. Fig. 3, is a central vertical section of same showing other details of construction. Fig. 4, is a cross section to illustrate one method of branching from and leading beyond the jet to supply the rim iushing means. Fig. 5, is a cross vertical section of Fig. 3, on theline at-Qc.A Fig. 6, isaplan of Fig. 3. Fig. 7, is a broken front external view of the lower part ot' Fig. 5. Fig. S,is a view partly in sectionof a simple hopper form of closet without flushing rim or siphoning trap, and supplied with a submerged jet and branch conduit leading therefrom to the rim of the bowl as in Fig. 4E. On Sheet 2, Figs. 9, 10 and 11, are views partlyin section s'howingone method of arranging the coiled conduit in the form of an annular reservoir below the normal Water line and above the seal and leading up to the rim of the bowl. Fig. l2, is a vertical section of a trapped closet provided with a siphon outlet and a downward directed jet above and discharging into the down legof said Siphon outlet, the conduit leading from said jetV being coiled vertically. Fig. 13, is a rear view of same, partlyin section, showing details of @on and jet. Y Fig. 14., is a modified side'view IOO of same showing the conduit torim delivery coiled horizontally around the front of the bowl above the normal water line. Fig. l5, is a sectional view of a double-trapped closet having a jet discharging downward into the space between the two traps, or beneath the seal of the lower trap as shown by dotted lines,or both combined,the rim supply being coiled vertically as in Fig. 12. Fig. 16 is an external view of a similar construction showing the rim supply branching from a jet at thelower trap and coiling horizontally around the bowl and up to the rim delivery.

The same letters of reference are used to indicate identical parts in all the figures.

The bowl A, Fig. 3, is trapped at d h, the inner wall d forming the seal.

Z is the normal water level mentioned in the declaration of the invention and Yis sustained bythe darn h. n

a is a flushing rim connected to the supply at the rim delivery b.

K is a supply or flush-pipe connected to an extension arm G of the bowl at 7.o, and branching directly to and connecting with the jet at c, as in`Figs. 1 3, 4 and 5.

E isa-guttered channel inthe back wall of the trap and e (as in all the sectional views) is a jet discharging into the trap. n

H, I, is a long .down leg extending from the trap D, H, and forming a siphon with its outlet t' lower than its inlet at d, and a horizontal extension from I to its outlet J forms a siphoning device as will hereinafter appear.-

Fig. 8, shows a simple hopper form of bowl having a jet ushing means but without a Iiushing rim or trap siphoning device, in which the conduit B branches from and beyond thejet as in Fig. 4, and rising directly to the'rm delivery b where it ushes the upper part of the bowl by means of the usual fan wash or spray. The supply pipe in Fig. 8 may connect with the jet and bowl by a coupling Yat c o'r by means of a connecting extension arm as shown in Figs. 1 or 9, or in any convenient way.

Branching from the jet e Figs. 2,4 and 5, is a conduit B which coiling backward passes between the short. and long legs of the siphon to the other side of thecloset, thence forward 'under the arm C, Fig. 1, and turning again at B2 coils around the fr ont to the reverse side of the bowl as at B3, Fig. 2, and rising connects with the rim of the bowl at the delivery b which point of delivery may be at any convenient point in its circumference for connection with the rim of the bowl, but for purposes of convenient illustration, I have shown it in all the views as connecting with the rim at the back above the trap.

In Fig. 9, the supply eXtensionO communicates with the jet e and the rim conduit B through a horizontal chamber at c, Fig. 1l, but-if preferred this connection and branch fmay be made as in Fig. 4. From the jet chamber c2 the conduit B, Fig. 10, rises and enlarges, to form a reservoir below the normal water line and above the seal, coils horizontally around the front of the bowl as in Fig. 11, and connects with the rim delivery b, Fig. 9.. From these constructions, even in the simple form of Fig. 8, it is obvious that the air in the supply pipe passing to or onto the entrance to the jet or carried by the current to the jet or to its entrance and there checked by frictional resistance to passage or escape through the conduit B will, obedient to the laws of gravity, follow the current, seek the nearest outlet, and naturally escape through the jet e and rise in bubbles to the surface in the trap. By arranging the conduit from the jet to the rim delivery in the form of coilsas shown in Figs. 1 to 6, owing to the length and turns in the passage, the dow is retarded,

. a back pressure is produced and a greater jet force results, as heretofore set forth. It' the down Siphon leg from Athe trap Fig. 3, was a straight return from H to J, as in Figi-S, the closet would not siphon by ordinary flushing means because the usual supply would not fill the down leg, but by the deflection H, I, .I means for accelerating the siphonic action is produced, and when the water flows into the closet in the ordinary way, owing to the turns in the tortuous passage, the incoming flow gathers Aupon the retarded fluid which backs or fills up to the level t' and forms a seal lower than the limb cl. of water fills the lower part of the down leg H, I, and a powerful Siphon results which Thus a solid body l ICQ empties the bowl and continues until the..

the surface line 1 rises for an instant and` then recedes as the fluid iiows over the dam at h, its outgo is retarded by the turn at 1,01,

a siphon results and the bowl is emptied as before described, but there is only enough water left to barely form a seal as shown by dotted line 3, which would soon evaporate and admit sewer gas, hence the importance of my annular reservoir B between the levels 1 and 3, in connection with the bow'l through an indirect or small opening, which in this instance is the jet e whereby the level of its contents' will be the same as in the bowl. Hence it follows that when the bowl is thus emptied by siphonage, the action is so quickly over that owing to its restricted communication caused by its tortuous return passage v vSealed conduit, preferebly forming an annular reservoir below the water line and above the seal and leading preferably from the jet to the rim delivery whereby in operationthe pressure upon the confined-air in the supply '.let through the jet by which means the air noiselessly escapes, the water is instantly started over the dam at h, the siphonic action follows and the bowl is emptied, b ut yowing to the elements of construction heretofore described, the whole operation produces no more noise than that of gently running water.

On Sheet 2, Figs. 12, 13 and 14, I illustrate a closethaving a single trap seal, a siphoning trap, H, I, J, anda downward directed jet at the top of the trap -at H. In closets o f this form it is usual to trap the supply pipe before communicating with ythe jet as shown by the outside coils of said figures, and which I do not claim and these figures are only introduced to show the application of my invenjtion to such construction by'supplying the rim flushing means of the bowl through a water sealed conduit leading from and beyond the jet to the rim delivery whereby the air must escape or be blown out through the jet as shown bythe vertical coil trap leading from the jet, in Figs. 12 and 13, down beneath the legs of the siphon and up to the rim discharge.

Fig. 14, shows a modification wherein the trapped conduit leading from and beyond the down turned jet coils around the front of the bowl above the normal water level 7i.

Fig. 15 shows a double trapped closet with jet at top or at bottom as indicated by dotted lines, or with both top and bottom jets combined and mytrapped rim supply leading from the jet delivery to the rim delivery, as in Fig. 12, by a vertical coil. Fig. 16 shows a similar construction with the jet also directed against or under the contents of the lower trap, and the rim conduit B branching from such lower jet and coiling horizontally around the bowl up to the rim delivery as in Figs. 1, 2 and 14. I prefer to trap the conduit leading from the jet flushing means to the rim iiushing means, beneath the normal level of waterin the bowl, but said conduit can be coiled or trapped above said water line and below the rim of the bowl in such manner as to be normally full of water. Hence I do not limit my invention to the precise forms of construction shown, as it is evident similar modifications will accomplish the same results, provided the supply pipe communicates first with the jet and thence by a conduit normally full of wa` ter which branches from and leads beyond said-jet to supply the rim iiushing means, whereby the air in the supply pipe may escape through'the jet flushing means and be prevented by the intervening and more slowly moving body of water constituting the seal in I claimsaid conduit from escaping at the rim ofthe bowl. Nor do I limit the'application ofthe coiled or trapped conduit to a receptacle having a tortuous outlet forming'a sphoning device, as it is obvious it could be used with a bowl like Fig. S having only a straight return trap and outlet. the invention to the precise forms shown for connecting the supply pipe to the receptacle or jet flushing means as any convenient method will answer the purpose.

Throughout the specification by the term supply pipe I mean the`conduit,'no matter how constructed, which carries the water to the jet.

Matter shown and described herein but not Furthermore I do lnot limit claimed, forms the subject matter of my `divisional application, Serial No. 485,773, filed September 19, 1893.
